RETURN APPLICATIONS
DOWNFLOW INSTALLATIONS
1. Position the unit to minimize long runs of duct or runs
of duct with many turns and elbows.
2. If summer air conditioning is desired, position the in-
door coil on the supply-air side of the unit. Ensure that
no air can bypass this coil.
3. If installing on a combustible floor and not using an
air conditioning plenum, install the special non-
combustible floor base. See Table 1 and Figure 11.
4. Connect the furnace to the supply air plenum.
5. Connect the return air ducting to the return air open-
ing at the top of the unit. Make the connection air tight
to prevent the migration of toxic fumes and odors in-
cluding carbon monoxide from migrating into the living
space from an adjacent fuel-burning appliance.
